ADJUSTABLE HIGH CHAIR.

Specification of Letters Patent.

Application filed October 9, 1909.

Patented May 3, 1910.

Serial No. 521,888.

To all whom it may concern:

Be it known that I, Hans P. HANSEN, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Adjustable High Chairs, of which the following is a specification.

This invention relates to adjustable high chairs, and one of the principal objects of the same is to provide an attachment for an ordinary dining room chair which can be quickly connected to the chair for accommodating a child.

Another object of the invention is to provide a high-chair attachment which can be quickly connected to an ordinary chair for use by a child and which can be readily converted into a chair provided with a high seat for grown people, or which can be readily disconnected from the chair and packed away in a small compass.

Still another object of the invention is to provide a high-chair attachment for an ordinary chair comprising a seat, a back connected to the seat, side arms hinged and pivoted to the seat so that they can be swung underneath the seat when not required for use.

Another object of the invention is to provide a high-chair attachment with a tray which can be swung up out of the way when not required for use and which will permit the chair to be readily converted from a childs high chair to a chair having a high seat for Various uses-by grown people.

Still another object of the invention is to provide a high-chair attachment for ordinary chairs, said attachment having means provided with adjustment for securing the attachment to any form of chair.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which,-

Figure 1 is a side elevation and partial section of a high-chair attachment connected to an ordinary chair and showing the vari ous parts in different positions in dotted lines. Fig. 2 isa front elevation of the same, showing the tray of the attachment thrown back and disposed at the rear side of the back of the attachment. Fig. 3 is a detail section through the tray and showing the manner of pivotally connecting said tray to a slotted bracket. Fig. at is a detail perspective "iew, showin the inner corner of one of the arms provid ed with a triangular slot for connection to a triangular bracket. Fig. 5 is a detail perspective view of a portion of the seat and back of the attachment connected together by a triangular bracket. Fig. (i is a side elevation of the chair attachment connected to an ordinary chair and shown in position for use by a child, a portion of one of the arms being broken away to show the manner of connecting the same to a triangular bracket secured to the seat and back. Fig. 7 is a front elevation of the same. Fig. 8 is a detail perspective view of a slotted bracket for pivotally and adjustably connecting the tray to the back of the high-chair attachment. Fig. 9 is a horizontal sectional view taken transversely through the back of an ordinary chair, and showing a modified form of seat for the high-chair attachment and means for connecting said seat to the back of the ordinary chair.

Referring to the drawing, the numeral 1 designates the seat of an ordinary chair supported upon legs 2 and provided with a back 3 having round side posts or supports 4.

The high-chair attachment comprises a seat 5 and a back 6 connected to said seat by means of a triangular bracket 7 comprising a base member 8 secured to the back and seat, and the bracket member 7 extending from one member of the bracket to the other, as shown in Fig. 5. The arms 9 of the attachment are provided with hinges 10 secured to their front edges, and one of the members of each of said hinges is pivotally mounted upon a pin 11 extending outward from the side supports 12 connected to the seat 5. The arms 9 are each provided with a triangular slot 13 at the rear end thereof and at the underside said arm is cut away as at 14, at the rear end thereof. On the front edges of the arms 9 catches 15 are provided to engage pivoted latches 16 connected to the underside of the tray 17, said tray being curved as shown and pivotally connected to the back 6 by means of headed studs 18 which extend through slots 19 formed in a bracket 20, said bracket having an extended arm or member provided with a slot 21 arranged at right angles to the slot 19 and piv-- otally connected to the tray by means of a headed stud 22 extending through the slot 21 and into the tray 17, as shown more particularly in Fig. 6. The arms 9 are connected to the side supports 12 by means of studs extending through the hinges 10, one of said studs upon one side being located below the other so as to permit the arms 9 to be swung outward on the hinge 10 and to be moved upon the studs 11 and swung underneath the seat 5, as shown in Fig. 1, one of said arms being disposed underneath the other, and said arms being held in position underneath said seat by means of hooks 23 secured under the seat 5 and provided with projecting fingers which engage the slots 13 in the inner ends of the arm members, as shown in Fig. 1. Formed upon the side supports 12 are rearwardly extending arms 2 1, and pivotally connected to these arms are slotted brackets 25 adapted to engage the posts 4 of the chair back, said brackets being held in adjusted position by means of thumb screws 26. The brackets 25 are each provided with a hook 27 which engages the posts 4, the opposite ends of said brackets being slotted, as at 28, to permit adjustment of the thumb screws 26.

As shown in Fig. 7, modified means are provided for connecting the attachment to an ordinary chair, said means comprising a seat 5 having supporting arms 6 pivoted thereto by means of studs 7*, said arms being provided each with a plurality of studs 8 projecting through arcuate slots 9 in the seat. This construction permits the arms 6 to be swung upon their pivots 7 inward and outward to permit the attachment to be connected to any ordinary chair, whether the posts 4 are located close together or farther apart.

The manner of using my high-chair attachment may be briefly described as follows :The high-chair attachment is connected to an ordinary chair by means of the slotted brackets 25. The arms 9 are held in upright positions by means of the brackets 7 when the tray 17 is thrown down and engaged by the latches 16 and the catches 15. When it is desired to fold the arms 9 under the seat 5 the tray 17 is thrown up to the position shown in Fig. 1, when the arms 9 may be thrown out to the position shown in dotted lines and swung upon their pivotal studs 11 and swung underneath the seat 5, where they are held in position by means of the hooks 23. The tray 17 may then be pushed down behind the back 6 of the attachment and between said back and the chair back 3, as shown in full lines in Fig. 1. In this condition the chair may be used by a grown person when desiring a high seat. If desired, however, the attachment maybe disconnected from the chair and packed away within a small'space.

From the foregoing, it will be obvious that a high-chair attachment made in accordance with my invention can be manufactured at low cost, can be quickly connected to an ordinary chair and adjusted in posi tion for use by a child, can be quickly folded in position for use as a high seat chair for grown people and can be readily disconnected from the ordinary chair and stored away within a small space.
